    Vermiculite Substrate for Mushrooms

    Our premium horticulture vermiculite is simply the best grade and variety for mushroom growers. We use Sun-Gro Premium grade Horticulture Medium vermiculite in all our products! Vermiculite absorbs water and is a key ingredient in many aspects of mushroom growing and fruiting. Vermiculite substrate is a popular add-on to almost any kit or growing project.

    • Use vermiculite for mushrooms to roll your colonized cakes in after dunking. This helps them stay hydrated and grow bigger.
    • Add a thin layer to any bulk grow and mist with water. This helps it absorb water and keeps the cake better hydrated to create bigger mushrooms.
    • Plus many more! Midwest Grow Kits’ vermiculite for sale will boost your mushrooms’ growth and always keep them hydrated.

    If you're a beginner and working with half pint cakes You will need this too do roll your cakes. Pound from pound not more expensive than Walmart or home depot. You can use this to make your own substrate with Coco Coir and gypsum.

    Love this Vermiculite!

    This is a MUST for any grower! Everywhere else I could only find the bigger chunks, this is really ground down into fine particles and my mushies love it! My only regret was not buying 4 gallons of it lol which I am ordering next! Thanks MWGK!

    Excellent product! I first used this with the starter kit. Later as I began using mini-tubs I re-ordered this vermiculite to add to my coco coir substrate. Works great and the price is very fair.

    Bigger pieces than my local stores
